It's not a need to mislead. You're grasping at a technicality. Citizenship is irrelevant if you're not given the chance to demonstrate it, which he wasn't, and again, he was actually deported because of the administrative error, not an on-purpose action, the correctness of which is irrelevant.
You're arguing whether a car wrapped around a tree has a bad alternator. Surely a fact useful to someone, somewhere, and worth knowing. But also certainly not the reason there's a problem.
100% this. To echo another poster below, it's really important to read the Supreme Court's own words here.
>"The Government’s argument, moreover, implies that it could deport and incarcerate any person, including U. S. citizens, without legal consequence, so long as it does so before a court can intervene. "

I suspect that is one of the main reasons behind the order. It's very obvious that citizen vs legal resident matters very little here, if due process is not given.
